After frequent use in winter, the PVC hot water bottle may require a thorough cleaning. A deep cleaning can effectively remove the tiny amounts of scale and internal deposits accumulated over the winter. Do not immerse the hot water bag in water, and avoid using hot water for prolonged steaming. After cleaning, you will find that the hot water bag feels much fresher, preparing it for use in the coming year.

Prepare about 40℃ warm water, add a small amount of baking soda powder and mix well. Pour the solution into the hot water bag until it reaches 1/4 of the capacity.

Gently shake the bag to allow the cleaning solution to fully contact the inner wall, especially covering the areas where water levels change regularly. Let it stand for 20 minutes.

Pour out the baking soda solution and rinse the inside with clean water repeatedly until the water flowing out is clear and free of impurities.

For external stains, use a cotton cloth dipped in diluted white vinegar water to gently wipe, then wipe the remaining residue with a clean damp cloth.

After cleaning, invert the hot water bag on a ventilated place to dry naturally. You can also use a clean towel to insert into the bag opening to absorb the remaining water droplets and keep the inside dry. 

Cautionary Notice：Do not immerse the whole hot water bag in water, and avoid using hot water for prolonged soaking. This can prevent the material from aging and deteriorating. After thorough cleaning, the hot water bag will become cleaner and more hygienic, and its lifespan will be extended.
